Subject: [PATCH 22/34] docs: filesystems: rename path-lookup.txt file

There are two files called "patch-lookup", with different contents:
one is a ReST file, the other one is the text.

As we'll be finishing the conversion of filesystem documents,
let's fist rename the text one, in order to avoid messing with
the existing ReST file.

 vfs now tries to do path walking in "rcu-walk mode", which avoids
 atomic operations and scalability hazards on dentries and inodes (see

+Documentation/filesystems/path-walking.txt). d_hash and d_compare changes
 (above) are examples of the changes required to support this. For more complex
 filesystem callbacks, the vfs drops out of rcu-walk mode before the fs call, so
 no changes are required to the filesystem. However, this is costly and loses
